Sandra Haynie needed four extra holes to beat Gloria Ehret in the $42,500 Lawsons' LPGA Open at Weymouth Valley (Ohio) Country Club, after she had fired a three-under-par 69 to tie Ehret at 215 for 54 holes. Haynie collected $5,700 for her first victory this year, her career 30th.

Easing her nervousness with self-hypnosis, CAROL SEMPLE calmly beat Angela Bonallack 2 and 1 in the final round of the British women's amateur championship at Royal Porthcawl links, in Wales. The current U.S. champ, Semple is the first American in 26 years to hold both titles concurrently.

HARNESS RACING—William Wellwood drove long shot SURGE HANOVER ($63.80) to victory in the $112,380 Dexter Cup for 3-year-old trotters at Roosevelt Raceway, clocking a 2.03[4/5] mile in a race marred by recalls (page 67).

It was the third consecutive Le Mans victory for the Matra team, which now has a solid lead in the world manufacturers' championship.

SOCCER—World Cup competition got under way in West Germany as early experts still favored The Netherlands. Johan Cruyff and his Dutchmen displayed their wares in a 2-0 victory over Uruguay, the outcome never in doubt, while Scotland soundly defeated Zaire 2-0. East and West Germany advanced with wins over Australia, 2-0, and Chile, 1-0, respectively. Italy triumphed over Haiti 3-1, Poland turned back Argentina 3-2 and Yugoslavia and defending champion Brazil played to a scoreless tie.

NASL: Powering along in the Western Division, Los Angeles remained undefeated, taking a game from Rochester 3-0 and pulling far ahead of second-place Seattle, which moved up from the cellar with a 2-0 shutout of Vancouver and a devastating 5-1 win over Baltimore. Newly acquired Striker David Butler may be the key, having produced four goals in as many games. The Eastern Division was deadlocked among Miami, Baltimore and Philadelphia. The Atoms stole a tie-break win from Boston 3-2 but lost another to New York 1-0, and suffered the same score against Washington. Last year's MVP, Warren Archibald, returned to the Miami starting lineup and contributed two goals and an assist in the Toros' 5-3 romp over New York. Baltimore got dumped 4-1 by Boston, but remained in contention with a 2-0 victory over Washington. In other action, Boston overtook Toronto in the Northern Division, beating the Metros 3-0, and Dallas nipped St. Louis 3-2 in a tiebreaker to regain the Central Division lead. St. Louis topped Toronto 1-0 and Rochester beat Denver 2-0.

TENNIS—BJORN BORG of Sweden (page 70) overcame a two-set deficit against Manuel Orantes of Spain in the final of the French Open to become the youngest player ever to win the French singles title.

In the women's singles CHRIS EVERT reaffirmed her role as Queen of Clay, not losing a set through the entire tournament and thrashing Russia's Olga Morozova in the final 6-1, 6-2, a win good for $8,000.

TRACK & FIELD—Poland's IRENA SZEWINSKA ran the 200 meters in 22 seconds flat at an international meet in Potsdam, East Germany, improving by one-tenth of a second the world record set in 1973 by Olympic gold medalist Renate Stecher of East Germany.

Bruce Jenner of San Jose, Calif. came from behind with a decisive second-day performance to defeat Jeff Bennett in the national AAU decathlon championship at Richmond, Va. A 4:13.6 victory in the 1,500-meter run added to his meet-record 8,245 points, 332 more than defender Bennett's total.

Discus thrower RICKY BRUCH of Sweden marked his 102nd consecutive victory with a 223'7½" effort at a local meet in Helsingborg. Bruch's performance, best in the world this year, was 9½" short of the world record of 224'5" that he shares with American Jay Silvester.
